Bis-propargyl-PEG3 is a crosslinker with alkyne groups at both ends of the molecule. The alkyne groups react with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry to form a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Attogene’s Carbon Dioxide Enzymatic Assay Kit is a simple, direct method for measuring Carbon Dioxide levels in the environment. The assay uses a coupled enzyme assay to detect CO2 (as HCO3-) as follows. In the first step, the bicarbonate condenses with phosphoenol pyruvate to form oxalate (and phosphoric acid); this reaction is catalyzed by the enzyme Phosphoenolpyruvate Decarboxylase, PEPC. The oxalate is then enzymatically reduced by the enzyme Malate Dehydrogenase (using an NADH cofactor) to form malate and NAD+.

The Phytase Assay Kit is a simple, quantitative method which can be used to measure phytase activity. Analysis is based on the hydrolysis of phytic acid by phytase and quantitative measurement of the phosphate released. Results are measured using a standard UV-VIS spectrophotometer and do not require the creation of a standard curve. The Phytase method can be used to measure phytase activity in cereal, fungal and bacterial phytases, and can also be used for the analysis of phytase in animal feed samples.
